is an option for Tree and related functions that specifies what style to use for subtree elements.


  • TreeElementStyle allows specifying the style of the root node of a tree, as well as that of any subtrees at positions matching a pattern.
  • The following option settings can be used:
  • Automaticuse the automatic setting for style
    styleuse style for the subtree element
    {pos1style1,pos2style2,}use stylei for the subtree element at relative position posi
    {patt1style1,patt2style2,}use stylei for the subtree elements at positions matching the pattern patti
  • Subtrees with no explicit element style are taken to use the automatic style.
  • To specify multiple style directives, use Directive[style1,style2,].
  • In TreeElementStyle, Allstyle uses style for all subtrees.

Basic Examples  (4)

Style an individual subtree element:

Style all subtree elements:

Use the same style for all subtrees:

Specify positions using patterns:

Properties & Relations  (4)

Styles for subtree elements can be specified by position:

Styles specified by a subtree take precedence over labels specified by its ancestors:

A position {i,j,} in a subtree refers to its subtree at relative position {i,j,}:

A relative position {2} at position {1} refers to the global position {1,2}:

In general, a pattern patt applies to subtrees at global positions {i,j,} that match patt:

A list of patterns {patt1,patt2,} applies to relative positions {i,j,} that match the patti:
